Good replacement for roomba
Delivered fast. Seems to be an exact replacement. Came partially charged so I used it for a while before charging. We'll see how long it holds up.

Fits, works, mine lasted only 18 months BUT THEY REPLACED IT FOR FREE
This kind of battery ought to be good for hundreds of charges.Unfortunately, my particular one had a bad cell and lost capacity after around 100 uses.After I gave them a one-star, they reached out to me and replaced the battery.EXCEPTIONALLY GOOD customer service

Cheap and easy to install, what more to love.
Why did you pick this product vs others?:It was a little cheaper to be honest! But it works great. Just five screws and bam! I’m so happy to have my roomba back in service for less than $20.

Returned but manufacturer replaced
// August 2025 update. The manufacturer reached out and offered to replace the battery. Charged the new battery overnight and the Roomba seems to be running well with the new battery.//Original Review. Returned due to the battery not taking any charge at all. Tested in two vacuums with two different docks.
